Split Dragons use their sharp teeth and wings to hunt large animals and rarely eat plants. They are intelligent dragons who enjoy mental challenges, preferably alone; Split Dragons are normally solitary except during mating season. When mating, many dragons come together in a group to raise their eggs and hatchlings. These groups tend to be very noisy—reminiscent of a thunderstorm—and last only until the hatchlings are capable of surviving on their own.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Two-headed dragons are unique enough to deserve a separate classification from ordinary dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, snapping back and forth. Their unique anatomy prevents them from breeding with single-headed dragons.

Endoroth is the oldest dragon in Pink's cave, and as such, demands the respect from all the dragons in her cave, even those that don't naturally have any. He and his friends -- Tegellin, Kosnek, and Skylune -- have survived multiple purges, cave revamps, and various other disasters that caused the loss of or exodus of many dragons. For that he's decided he deserves a quiet retirement. He generally keeps to himself, but will occasionally venture out to breed and care for an egg with his beloved Enellith, or examine some of the newer additions to the cave. He's especially baffled at the variety of dragons nowadays. He especially is curious about Swallowtails. Their two tails strike him as such a novelty. He doesn't fly much any more, but still enjoys sitting with his mate and watching the younger dragons fly about and preform their aerial acrobatics.
